T a/ZZ whom it mfcty cora/cern.-

Beit known that I, ERIC HEDRURG, va citizen of the United States, residing at Joplin, Mis-i souri, have invented certain new and useful .top of the water, are not carried along and passed out with the current, as has been the case with apparatus of this kind heretoforev used, but are collected and saved and caused to settle in the Orebed with the coarser ores. I have illustrated my invention in preferred form in the accompanying drawings, in-

which- Figure 1 is alongitudinal sectional view ofy my invention. Fig. 2 is a cross-sectional view of the same. Fig. 3 is a perspective detail of one of the partitions.

In carrying out the invention I have constructed the jig with the usual ore-beds A,

each being provided with a hutch B and being separated by partitions b. Any number of compartments desired may be provided, usually from five to seven. The bottoms of the ore-beds are covered with a fine screen or sieve, through which the line metal drops by gravity. The ore is fed into the jig at C and settles into the different compartments, the fine minerals settling into the hutches B. Water is supplied to the jig through the trough C from any suitable source of supply and is kept constantly iiowing over the orebeds .A and passes from the jig through the spout D. When in operation, the ore-beds are kept agitated by the operation of the jigplungers E, which are connected to and operated by the eccentrics E', which are mounted upon a shaft driven by any suitable source. of power.

In ore-jigs as heretofore constructed it has been impossible to save the fine ore-slimes which float upon the surface of the water and are carried off with it, as it passes over the sieves and is lost with the overflow.

As shown in the drawings, I have provided` l Specification 'of Letters Patent.

one partition tofgravitate into the ore-bed A of the next partition, and so on through the ndifferent compartments. The ore bed or screen inthe first compartment at the receiving end Cof the jig is placed near the topof theirst partition b, and the screens in each of the succeeding compartmentsl are placed slightly ,lower than the one preceding it. It willthus be seen thatthe tops of the partitions Z) and the ore-beds are arranged on an angle from the receiving end C to the discharge D of the jig.

In the frame of the jig I `have provided vertical grooves e. F represents partitions or defiectors which are provided at each end thereof with a spring f. These deflectors F are made of a size adapted to slide in the vertical grooves e in the jig-frame and are held in position by the pressure of the springs f.

In operation the partitions or deectors are adjusted to position in the grooves and are extended below the surface of the water, as shown. The line ore which iioats upon the surface of the water will pass over the top of the partitions b until it comes in contact with the iirst deflector F, which will throw it into the suction of the ore-bedof the next compartment, where it will settle and pass through the screen in the ore-bed of that compartment. Any of the finer suspended particles of ore which might be drawn by the current of water over the partition I) will come in contact with the Vsecond deiiector and be thrown into the suction of the ore-bed of the neXt compartment and there settle to the bottom, and soon until all of the fine ores have been preserved. For ordinary use I have found it desirable to use two or three of these deflectors in the jig; but it is obvious that any number might be used as found desirable in order to deflect all of the finer particles of ore which otherwise are carried upon the surface of the water and lost in the overflow.

It will thus be observed thatI have provided a simple and effective arrangement for securing and preserving all the fine metals in the Ore. I do not desire to limit myself to the construction shown in the drawings, as the details thereof may be changed without departing from the spirit of my invention, which consists, essentially, in providing means for arresting and settlingthe ore-slimes iioating with the current of Water passing over the ore-beds.

IOO

Obviously the partitions or defiectors need not be of the number, shape, or size which I have shown and need not have the 4spring arrangement for holding in place and need not be disposed therein in grooves` as I lhave shown; but any other manner of disposing these partitions or deiectors so as to create a 'still surface in the water passing through the jig and allow the ore-slimes to settle and be passed linto the hutches I should contemplate as coml tially as described.

2.' An ore-separator provided witha pluralv ity of sections, a plunger-compartment in each 1 section and a plunger therein, a hutch at the bottom of each section a screen 4ore-bed Inear the Itop of each of said hutches, ladjustable deflectors or partitions between the sections, the walls of said sections having grooves in which said partitions may slide, said partitions adapted to form lpassages in close proximity to the ore-beds andto deiect the ner ores into the ore-beds, whereby said finer ores may work through the screens into the hutches, substantially as described.

3. In combination with aplunger-jig, a plurality of jig-sections having ore-beds located at different heights between said sections, hu'tches beneath said ore-beds, adjustable partitions having springs upon the ends thereof, the walls of said sections having grooves into lwhich said partitions may slide, said partitions adapted to form passages in close proximity `to the ore-beds, and to deflect the liner ores into the ore-beds, whereby said finer ores may work through said screens into the hutches, substantially as described.

In testimony whereof Ifha'vehereunto signed .this specification in the presence of two subscribing Witnesses.
